PUSH-BUTTON nppiicatmn :ned Jennery To all whom it may concern.' y

Be it' known that L'Rdnx-:n'r E.

' residing .at Detroit, in the',A 'county of Wayne and State of lilichigan, have invented cer-A tain new and useful Improvements in Push- Button Constructions, of which the followingSis a specification, reference being;r had thereinto the accompanying drawings. Thisinvention relates to a. push button construction wherein :reap or inger'piece. is depressed to establish un electrical connection between contact members, and l have improved such construction in twoparticulars.

First, I provide novel meansforretaiu-l ing-the cap on the bod;1 or nut so that the snmemay lbe actuated without any danger of the cup becomingr accidentally displaced.

The means employed for thispurpose includes aY split ring or member whlch is an chored in the cp to more therewith and exs tends into a groove in the body or nut with the groove of sufficient Width to permit of the cap being actuated.

Second, the Contact members are in the form of rivets mounted in an insulator or support, and the leading-in conductors have the inner ends thereof positively anchored by the rivets so that therey will he a positive electrical connection between the conductors and the rivets.

hy improvements will be hereinafter more fully described and then claimed, and reference will now he had to the drawing. where- 1n- Figure 1 is u cross sectional push button;

Fig. 2 is n transverse sectional view o the push button, purtl)7 in elevation;

Fig. 3 is a horizontal sectional View of the push button, partly in plan;

Fig. 4 shows perspective views of different parts of the push button;

hg. o' is an enlarged detail sectional view of an .insulator or support provided with n. contact member. and

Fig. is n. bottom plan of the same.

In the drawing'. the reference numeral 1 denotes a bod)` or nut adapted to he'fmounted on the steering column assembly of an automobile or other vehicle so that the push button may forni part, of the electrically operated or alarm system of the automobile. The nut 1 has a cylindrical portion 2 end view of the Seeheim a. citizen' of 'the UnitedStatesof America,

the" 'annular wall of this portion of, the nut is provided with an annular veBL Slidable on the cylindrical` portion 2 of the nut lis a. cap or finger piece 'its annular inner wall provided 4,nular groove 5 for a, s' lit ring or member 6 `which snugly Hts in t e groovevjand protrudes in'to the groove 3v of ithe nut, said groove being of a width permitting of the cap 4 shifting on the cylindrical portion, 2 of the nut l, when depressed, Wifhoutnhyfdanger ot .the cap i becoming accidentally displaced.v 0n the cylindrical portion 2of the nut 11 is a. washer 'Z 'made of ,insulntion vmaterial and on the washer? is a support 8 also made of insulation material. Mounted in the sup-'uI port 8 are two'irivets 9`-and 10, leach having.. countersunk heads push button as being flat heads il und flared l2. ,Considering the l used in a vertical -positionthe heads 12` nre countersuuk in the flower, .face of thousupport S and are prevented Afrom coming'V in contact with metallic partsLsnch asthe nut 1 or asteering" shat, ;bythe washer 7. The support 8 and'under.4

heads 11 are abovethe the'head'. l1 ofthefrivetl is anchored the ends of a. resilient bowedl Contact member or arm 13 which has a bowed end 14 thereof extending above the head 11 of 'the rivet 9 to Contact therewith when the cap or nger piece 4 is depreed. In the oep or finger piece 4 is 'a washer or weer member 15 preferably made of insulation materint as fiber.; and the resilienov of the contact member 13 causes seid mouiller to hold-the weer member 15 normally shown in Fig. 1.y

The side wall if theV cap 4 has an opening 16 and extending through said 'opening are leading-in conductors llvrhich .are held t0- gether and protected, at'the. wallsof the opening 16, by a sleeve or band 18 mounted on said conductor. l

The inner ends of the conductor 17 are hared and the strands or wires of each conductor separated or spread a `artas shown in Fig. 6, so that the straus or wires 19 may he placed in the rivet holes of the support 8 and lie comparatively dat under the head 1l of each rivet and at the same time positively enga each rivet, particularlj.;r the countersun heads 12 thereof, as best shown in Fig. 5. The bared ends of the wires are snugly held in engagement against thefcap 1 4, as `liest with the support 8, insuring a positive electrical connection between the conductors and the rivets and permitting accidental displacement of said conductors.

In order that the rotatable cap 4 may be removed, said cap has a side opening 20 into which may be inserted n suitable tool to-engage and force a portion of the ring 6 from the groove 5, so-that the cap can be forced off or sprung'from the nut without injurgr to either. My improvements provide a push button of better construction than an ordinary ush button. and while in the drawing there is illustrated the construction which I am now manufacturing yet I-reserve the right to make such changesas fall within the soupe of the a' nded claims.

1. In a push button construction wherein a nut is provided with a cap or linger piece adapted to be depressed to e ect an electrical connection between a stationary Contact member and a movable contact member, Whichmovable member holds said cap nor- Vniaily `distended relative to said nut, and a leading in condnctor;-means articulating said nut and ca to prevent displacement of the latter an permit said cap-to rotate relative to said nut, said means including a split ring, `said cap having a. groove in its inner wall to receive said r' and said nut having a groove to receive sai ring, the nut groovebemg of suicie'nt width to permit said ring no shift therein during depression of said cap, and said cap having a side opening to rivet said leading in conductor so that said conductor by 'virtue of said rotatable cap may be conveniently placed.

2. In a push button Construction wherein a cap is depressed to establish an electrical connection betweenoontaot members,said members comprising rivets, an insulator support for said rivets, the rivets havin dat heads on said support and countersun heads in said support, a conductor extending through an opening in said cap and havi strands thereof held by the countersunk eads of said rivets, and a resilient bowed contact arm held,l under .the dat head of one of said rivets and 'extending over the dat head of the other of said rivets and adapted to be sprung by said cap to engage said head and estab ish the electrical connection.

3. A push button com rsn a normally stationary nut, a rotate le an depressible cap on said nut, said cap having a side opening, Contact members betwell Said Cp and nut adapted to close an electric circuit when said cap is depressed, and a leading in conductor-extending through the cap opening and connected to said contact members, said cap rotatable to permit of said conductor belng convenient y placed relative to Said nut.

In testxnon whereof I aix 4my signature 1n presence o two witnesses.
